I got that same email. I'm reassured hearing you did, too, in that at least I didn't do anything weird -- just something funky on their end. It's their first year.
Iowa rejection was via email. Just heard from Stanford via email - notice to check the application decision on their site...which was a no. Just a little more build up for the same result so far. Down to Duke and Northwestern.
Got the official "no" from Iowa MFA film program and UT-Austin MFA film program. Waiting to hear from Duke, Stanford and Northwestern (all documentary MFA).
